Study of Cisplatin-Induced Peripheral Neuropathy in Patients With Germ Cell Tumor

This is a prospective observational study investigating the incidence, characteristics of, and change in chronic neuropathy symptoms related to cisplatin using the EORTC CIPN-20 instrument. Approximately 60 patients will be collected for this study. The duration of this study will be up to 18 months for each patient. This study will complement a current R01 funded trial (Platinum Study) which evaluates the genetic predisposition of chronic neuropathy after 12 months of chemotherapy. However, although the platinum study evaluates a similar patient population, it does not evaluate the natural history of platinum induced neuropathy during active treatment and the first 12 months post chemotherapy. This trial will fill this gap and add to the investigators knowledge for both natural history and genetic predisposition of platinum neurotoxicity.
